Detailed description of the invention
Fig. 1 is identification process figure of the invention.
Fig. 2 is switchgear front view of the present invention.
Fig. 3 is inside switch cabinet structural schematic diagram of the present invention.
Specific embodiment
Presently in connection with attached drawing and preferred embodiment, the present invention is described in further detail.These attached drawings are simplified
Schematic diagram, the basic structure of the invention will be illustrated schematically only, therefore it only shows the composition relevant to the invention.
Such as the position judging method based on image recognition in a kind of Fig. 1 to switchgear shown in Fig. 3, under nominal situation or cabinet
Under exfactory inspection eligible state, chassis vehicle 1 exists in test position, working position, valve in initial bit, stop bit, earthing switch 2 son
When quartile, coincidence, the video image of multiple cameras is carried out screenshot by video server respectively and saves conduct by daemon software
Initial pictures, when these three components in the process of running, real time video image that daemon software captures each camera with
Above-mentioned initial pictures are compared, and by simply measuring the positional distance on image, calculate chassis vehicle 1, valve, earthing switch
The actual range that video image in 2 motion processes is differed with initial pictures, with this come judge motion process it is whether normal and
In place whether position.
It include: image capture devices, server, power supply mould for the reckoning system in switchgear based on image recognition
Block, interchanger and background devices；Image capture devices are for being continuously shot chassis vehicle 1 in switchgear, valve and earthing switch 2
Equipment, power module be it is commercially available, and image capture devices, server and exchange mechatronics, and be image capture devices,
Server and interchanger provide power supply, image capture devices and server electrical connection, and by the image transmission taken to service
Device, server are electrically connected by interchanger and background devices, and the image data received is transferred to backstage by interchanger
Equipment.
In view of the light problem in switchgear, the commercially available infrared night vision wide-angle camera 3 of image capture devices, infrared night vision
Wide-angle camera 3 can clearly shoot the image of chassis vehicle 1, valve and earthing switch 2, infrared night in dark switchgear
The quantity of wide-angle camera 3 is regarded as three, chassis vehicle 1, valve and the earthing switch 2 being respectively aligned in switchgear, and individually and
Server electrical connection, infrared night vision wide-angle camera 3 is by the image taken with analog signal output；Analog signal passes through cable
Be transferred to server, server is the video server that commercially available multichannel inputs single channel output, video server receive one or
The analog signal that more infrared night vision wide-angle cameras 3 issue, by cable to interchanger output digit signals, interchanger is city
The network switch of purchase, the network switch and video server are connected by cable, and the network switch and background devices pass through net
Line connection, background devices are to be equipped with the backstage of commercially available image recognition software, such as server, the end PC or cloud processing end.
And, headlamp is always on the general camera of Shi Keyong instead of infrared night vision wide-angle imaging when self illumination lamp in switchgear
First 3.
A kind of interior position judging method based on image recognition of switchgear, comprising the following steps:
A), switchgear, interior 1 position of chassis vehicle, valve position and earthing switch are obtained using infrared night vision wide-angle camera 3
The image of 2 positions,
B), the image obtained in step a) judges 1 position of chassis vehicle, work in switchgear after image recognition software identifies
Door position and 2 position of earthing switch whether in specified position,
C), image recognition software identification decision in step b), 1 position of chassis vehicle, valve position and ground connection are opened in switchgear
One or more of 2 positions are closed not at specified position, that is, take component position and original image location in image,
When value range beyond setting, signal an alert.
Specific detection process is as follows:
In the detection process for earthing switch 2, sufficiently to extract characteristics of image, static region is avoided to interfere, first
3 shooting area of infrared night vision wide-angle camera is intercepted using Rect rectangle class, is in addition examined to guarantee that earthing switch 2 is closed
That surveys is absolutely accurate qualitative, improves detection accuracy using multimode combination detection principle in 2 occlusion detection of earthing switch.Mainly
Detection means is closure Hough loop truss and probability Hough straight-line detection.Video image is carried out Gauss first by the detection means
Filtering processing and gradation conversion processing, to reduce interference and improve silhouette contrast degree, then with threshold width appropriate to figure
As region progress edge detection and binary conversion treatment, target image profile binary image is obtained, is finally used
Image is carried out three-dimensional space conversion by HoughCircles and HoughLines method, and detects earthing switch 2 and horizontal line
Angle and earthing switch 2 on circular contour exported with closed position relative position.
In the detection for switch cabinet shutter, mainly uses color space conversion technology and pixel value extracts skill
Art.It acquires video selected characteristic region first against infrared night vision wide-angle camera 3 to be intercepted, to reduce interference, with laggard
Row image gaussian filtering and edge detection.Then RGB is carried out to video image to convert to hsv color space to carry out next
Histogram equalization and pixel extraction.Under switchgear enclosed environment, it can be obtained by formulating pixel extraction to HSV control
Valve dynamic position pixel, to further increase position detection accuracy, system has carried out serial opening and closing using morphologyEx
Operation carries out profile again to HSV image and mentions to reduce salt-pepper noise interference and the interference of profile non-occlusion region, subsequent system
It takes, obtains valve precise edge position, handled by pixel position equilibrium evaluation, obtain valve physical location and exported.
For in 1 detection process of chassis vehicle, the preferable side breaker of light conditions is had chosen first and is detected, it is right
After image-region is filtered, grayscale image is converted and a series of processing such as edge detection, breaker precise edge position is obtained,
Since there are the projections of top shade to interfere in 4 detection process of breaker, three phases are divided to be respectively adopted 4 stroke of breaker herein
Acquisition 4 physical location of breaker is exported after specified area pixel point counting mode carries out position judgement.
It is a specific embodiment of the invention described in above instructions, various illustrations are not to reality of the invention
The limitation of matter Composition of contents, person of an ordinary skill in the technical field can be to described in the past specific after having read specification
Embodiment is made an amendment or is deformed, without departing from the spirit and scope of invention.
